Eric,
    Does that mean the Customer will not set TOS byte in the data packet?

Then when the data packets are coming at the ingress point of the MPLS
Domain, how will it be known, to which Diff Serv LSP, the packet has to be
sent, since DSCP value is not set in the header.

Then, who will set the DSCP value?
